ggdag: Tidy Analysis and Plotting of Directed Acyclic Graphs

An R package for analyzing and visualizing directed acyclic graphs (DAGs), built on the 'dagitty' package and the DAGitty web tool. It provides functions to tidy, plot, and analyze DAGs using the 'ggplot2' and 'ggraph' ecosystems. The package was created by author Malcolm Barrett.

Use Cases

• Visualizing causal diagrams based on the plotting capabilities with 'ggplot2' and 'ggraph'
• Identifying adjustment sets for causal analysis based on the analytic functions mentioned
• Determining relationships between nodes in a causal model based on the node relationship functions
• Tidying and preparing DAG objects for further analysis based on the tidying functionality

Strengths

• Built on the established 'dagitty' package and DAGitty web tool for DAG analysis
• Integrates with the widely-used 'ggplot2' and 'ggraph' packages for consistent and customizable plotting

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Row count and data scale are unknown, which may limit suitability assessment
